§ 6.08.010. Prohibitions and restrictions generally.

A.

No User shall contribute, or cause to be contributed to the District's Sewer System, directly or indirectly, any pollutant or wastewater which will pass through or interfere with the system or the POTW. These specific prohibitions apply to all such Users of the District's Sewer System whether or not the User is subject to National Categorical Pretreatment Standards or any other National, State, or local pretreatment standards or requirements. A User shall not contribute the following substances to the District's Sewer System:

1.

Any liquids, solids, or gases, which by reason of their nature or quantity are, or may be, sufficient to cause fire or explosion or be injurious in any other way to the POTW or the operation of the POTW, including, but not limited to, wastestreams with a closed cup flashpoint of less than one hundred forty (140) degrees Fahrenheit (sixty (60) degrees Centigrade) using the test methods specified in 40 CFR Part 261.21, gasoline, benzene, naphtha, solvents, and fuel oils. At no time shall two successive readings on an explosion hazard meter, at the point of discharge into the system (or at any point in the system), be more than five percent, nor any single reading over ten (10) percent, of the Lower Explosive Limit (LEL).

2.

Any waste which cannot be carried freely under normal flow conditions prevailing in the District's Sewer System. This prohibition shall apply to, but not be limited to, solid or viscous substances which may cause obstruction to the flow in a sewer, or other interference with the operation of the POTW such as grease, garbage with particles greater than one-half inch in any dimension, animal guts or tissues, paunch manure, bones, hair, hides or fleshings, entrails, whole blood, feathers, ashes, cinders, sand, spent lime, diatomaceous earth, stone or marble dust, metal, glass, straw, shavings, grass clippings, rags, spent grains, spent hops, waste paper, wood, plastics, gas, tar, asphalt residues, residues from refining, processing of fuel or lubricating oil, mud, or glass grinding or polishing wastes.

3.

Any wastewater having a corrosive property capable of causing damage or hazard to District structures, equipment, or personnel, but in no case wastewater with a pH below 5.0 or greater than or equal to 12.5 units at any time (instantaneous standards), or which will change the pH of the District's discharge to IEUA's regional interceptor to less than 6.0 pH units or greater than 9.0 pH units.

4.

Any noxious or malodorous liquids, gases, or solids, which either singly or by interaction with other wastes, are sufficient to create a public nuisance or hazard to life, or are sufficient to create a public nuisance or hazard to life, or are sufficient to prevent entry into the sewers for maintenance and repair.

5.

Any wastewater with a temperature higher than one hundred forty (140) degrees Fahrenheit (sixty (60) degrees Celsius) at any time.

6.

Any radioactive wastes except:

a.

When the User is authorized to use radioactive materials by the State Department of Health or other governmental agency empowered to regulate the use of radioactive materials; and

b.

When the waste is discharged in strict conformity with current California Radiation Control Regulations (California Code of Regulations, Title 17) for safe disposal; and

c.

When the User is in compliance with Title 6 of the District Code and all other applicable rules and regulations.

7.

Any wastewater which causes a hazard to human life or creates a public nuisance.

8.

Any "emulsifying agent" that suspends or emulsifies any fats, greases or oils and is specifically used to prevent oil and grease build-up in any gravity separation device or interior plumbing.

9.

Any petroleum oil, non-biodegradable cutting oil, or products of mineral oil origin in amounts that cause pass through or interference.

10.

Any discharge from any vehicle radiator, including but not limited to, radiator fluid or radiator flush chemicals.

11.

Any overflow from a septic tank, cesspool, chemical toilet, or any liquid or sludge pumped from a trailer, bus, and similar vehicles having wastewater holding tanks except at such place and in such manner as may be prescribed by the General Manager.

12.

Any waste transported from one location or facility to another for the purpose of treating or discharging it directly or indirectly to the District's Sewer System without written permission from the General Manager.

B.

Significant Industrial Users shall comply with all regulations, permitting, and reporting requirements established by IEUA.
